Our chimneys are free-standing structures without pull off systems. The chimney is made of G-235 steel pipe. The chimneys are delivered in parts which are joined together on customer’s site. The are also covered with a silicate-zinc paint and a heat resistant enamel. The silicate-zinc paint after it has dried up makes coating comparable to zinc coating.
For boiler rooms with higher heat load and to improve the operation of the boiler, it is recommended to use of chimneys with forced controlled draft – the A1x630 and A1x630 with an ash cyclone and flue draft VFD fans. The usage of the ash cyclone with the flue draft fans allows a customer to use a smaller chimney. We can custom manufacture flue connection from the boiler to the chimney.
Recommended diameter and height of the chimney with KWH boiler:
Chimney with ash cyclone
Chimney without ash cyclone
|[model]||Cyclone [model]||Fan [kW]||Diameter [mm]/[in]||Height [m]/[ft]||Diameter [mm]/[in]||Height [m]/[ft]|
*These are only recommended chimney heights and diameters. Instead of height, draft could be increased by draft booster/ ash cyclone blower.*
In standard version the chimney are made of pipes of following dimensions [mm]: 219×6.3, 323.9×7.1, 610×10, 813×12.5
